2. What is
CompleteCNG?

3. What is CompleteCNG?
CEC’s CompleteCNG includes
proven CleanCNG technology in a
package that combines portability
with configurable plug-and-play
installation.
The self-contained system has a
smaller footprint than a standard
built-in station and requires minimal
on-site construction, making it fast to
install and easy to relocate. CEC
designers and engineers have
responded to the needs of the
market to deliver a comprehensive
sustainable CNG fueling system with
minimal environmental impact.

CompleteCNG Station
How many trucks can CompleteCNG fill at once?
This is a proposed site
layout for a Refuse site
utilizing the CompleteCNG
fueling system. Using eight
time fill houses (four
modules) it is possible to
fuel eight Natural Gas
Vehicles at once.

Compression?
5 Exclusive Advantages

11. CEC Exclusive Advantages
CEC’s non-lubricated compressors
set the global standard for minimum
oil carry-over in CNG compressors
without the waste, cost and negative environmental
issues of additional filters, auto oil drain systems and
supplementary oil tanks. Only 5 parts-per-million or
less vs. 100 PPM or more.
 Lower operating costs: Oil litres/year: Lubricated
systems= up to 1200 vs. IMW = 80 in crankcase
 Lower maintenance costs: no oil accumulation in
compressor or vehicle systems. Happier
customers and increased station profitability.
 Inside a CNG vehicle, onboard CNG stored at
3600 psig is regulated to 100 psig by a regulator
and then injected into engine. There are many
examples of oil soaking the regulator diaphragm,
affecting its accuracy and, in some cases, causing
a rupture of the regulator internals if oil clogs the
regulator.
The majority of engine performance
issues are attributable to oil carryover,
which is a problem that begins at the
fueling station.

12. CEC Exclusive Advantages
CEC is the largest and
only exclusive manufacturer of
non-lubricated CNG compressors
globally making us a proven
manufacturer with the world class
experience you need supporting you
 A century of manufacturing
experience
 3 decades of non-lubricated
CNG compressor
manufacturing experience
Sales
Service

13. CEC Exclusive Advantages
The best durability and reliability in
the industry
 CEC has the most northerly long term
operational installation in the world in Barrow
Alaska, which, combined with our installations
in Qatar demonstrate reliable commercial
operation across more than a 110oC temp
range and some of the most abusive conditions
on earth
 Gas dryers are installed on low pressure inlet
not the high pressure discharge, keeping
CECC compressor system dry with better
chances of not freezing during the extreme
temperatures of winter.
 Existing installation in South America still
running at 70,000 hours

14. CECC Exclusive Advantages
CECC is the only manufacturer
offering advantages of multiple
modular configurations
• Allows for variable supply for higher
efficiency at low demand periods
• Full redundancy and enhanced reliability

15. CECC Exclusive Advantages
The only manufacturer that
covers the widest spectrum of
compression requirements with
a single block instead of
multiple, unique machines:
• Less training required – better
maintained machines
• Common parts – lower inventory, lower
cost of ownership
